Specification of Letters Patent.

1' gall whom it may concern: 1 gee it .known that 1, JOHN OQonnon,eicitizen of the llnited States, residing at Ghicago, in'the 'county ofCook and State in the drawings forming a ,part of this.

specilication, Figure 1 is a plan view of a draft rigging embodying myinvention;

Fig. 2 is a vertical longitudinal section on line 2-2 of Fig. 1; Fig. 3is a cross section on line of Fig.2.

Referring to the drawings, the numerals indicate draft sills or parts ofthe car frame to which the draft rigging is'applied 5-5 represent cheekplates, draft lugs or side castings, the same being oppositely ar rangedbetween the draft sills, and each being secured to the adjacentsill byany suitable means, preferably the rivets 6 6.

The numeral 7 indicates a. draw-bar, only the rear portion thereof beingshown in -the drawings, having a transverse slot 8 to re oeive thecoupler-key S), which passes through slots 10 in the adjacentliuibs'of'the draft yoke 11" and through slots l2l2 in the draft, sills.Each cheek plate, draft lug or side casting 5 is provided with apreferably integral housing 13 to receive an end of the shoe 1%. Theshoe 14: is mounted between the cheek plates, draft lugs or sidecastings 55 and is preferably of a general cylind rical shape, thelower; face 15 thereof being squared and having a. recess or groove 16therein. The housing 13 at either end of the shoe l4 conforms in shapeto the adjacent faces of the shoe, the lower opening 17 of each housingbeing of a lesser Width than the (llulTMItGlUO'f the shoe 1 to preventthe downward displacement of the shoe. A bolt 11%, or other suitablemeans, is passed through the shoe l land through suitable perforations19 in the upper ends of the upper set 20 of platesor springs, the saidplates alterniitin'g in their arrangement with the plates or springs 21of the lower set-of springs.

Patented May 4, 1915. 1

Thelow'r springs 21 are received in a groove or recess 22 in the upperface of a shoe 23, which is similar in construction to the shoe 14, thelower set'of'plates 21 being held in said recess by a bolt 24 passingthrough the said shoe, preferably at its middle portion. The ends ofthe'lower shoe 23 are received in, and home by a housing at either end,each of said housings 25 consisting preferably of a separable memberreceived Within a slot 26 in the lower central portion of a check plate,drafting or side casting Each of said housings 25 receives an end of theshoe 23 withinits appropriate recess 27, the walls of said recessconforming to the adjacent bearing faceof the shoe 23.

The upper and lower spring" plates pass through a vertical opening 30 ina block 31 which is received Within the yoke 11, its sides engaging thelimbs 3131 of the yoke in preferable arrangement, and its forward andrear ends preferably engaging the draW- bar 7 and the rear member of theyoke 11, respectively. The front and rear walls forming the opening 30in the said block are convex, as illustrated in Fig, 2-of the drawings.

In mounting the compression resisting parts of the draft rigging betweenthe draft sills, the upperset of springs is inserted in the shoe l4, andsecured therein by the bolt 18, the said springs being passed throughthebpening' in the block mounted within the yoke, and thereupon thelower housings 25, with the lower set of springs and lower shoeassembled therein, ore-passed 'into position from underneath, the lowerhousings then being ui'ipropriately secured to the sills anl sidecastings preferably by the bolts ltd--35. The upper faces 3636 of thelower housing, IliOtIilJQiS support the block within the yoke and alsosupport the yoke, the limbs of the yoke and the block being in slidingengagement therewith in 100 the operation of the gear.

()n forward movement of the draw-bar,

the blook withintlie yoke is drawn fol? wardly, its movement beingresisted by the from the secured ends of the other set. 'The forwardmovement of the block is limited 9 Springs passing through the block,the

by the confor fiii tion of the sprin gs to convex rear face formingtheopening 30 through the block. During the forward movement of thedraw-bar, the upper and lower shoes rotate in their respective housings.

On rearward movement of the draw-bar,

the, block Within the yoke is moved rearwardly, the upper andlower shoesrotating in their respective housingsas the sprlngs are rearwardlyflexed. The frictional action between the upper and lower sets ofsprings occurs in a manner similar to that described upon forwardmovement of the draw-bar,-

the rearward movement of the block being limited by the'conformation ofthe springs to the convex face forming the forward wall of the openingin the block.

1 claim:

1. In a draft rigging for railway cars, in

combination, draft members, a draw-bar,

cheek plates, draft yoke connected to the draw-bar, a slotted blockwithin the draft yoke, two sets or spring plates, upper and lowerrotatable shoes,

I and separate housings- "ior the lower shoe, the cheek plates beingprovided with housings to receive the upper shoe, nected at one end tothe upper shoe, the

' other set of spring plates being connected at one end to the lowershoe.

2. In a draft rigging for railway cars, the combination withdraftmembers having cheek plates secured thereto, of an upper shoeextending from one cheek plate to the other and mounted in bearingscarried by said cheek plates, a lower shoe extending one set of springplates being con from one-cheek plate to the other cheek plate androtatably mounted in bearings carried thereby, and spring plates securedat their ends in said shoes.
